PHP/NoSilencedErrors: remove tolerance for parse_url()

[jrfnl]

Description

The parse_url() function was in the list of functions allowed to use error silencing due to it throwing an E_WARNING in certain circumstances in PHP < 5.3.3.

I believe by now, we should no longer need to take PHP < 5.3.3 into account, so this exception should no longer be permitted.

Suggested changelog entry

WordPress.PHP.NoSilencedErrors: error silencing is no longer accepted for the parse_url() function.

LGTM! For reference, the PHP bug report confirming the E_WARNING was removed in PHP 5.3.3: https://bugs.php.net/bug.php?id=50563. And here is a 3v4l.org snippet showing the warning on PHP < 5.3.3, and no warning on any currently supported PHP version: https://3v4l.org/04lvl

Indeed. It used to also be in the docs, but references to PHP 5 were removed from the docs a couple of years ago.
You can still see the old docs here though: https://php-legacy-docs.zend.com/manual/php5/en/function.parse-url#refsect1-function.parse-url-changelog
